SPECIFICATION forming part of Letters Patent No. 410,456, dated September 3, 1889.
Application filed April 20, 1889. Serial No. 307,981. (No model.)
To all whom it may concern.-
Be it known that I, FREDERIC SHULS, a citizen of the United States, residing at Galion, in the county of Crawford and State of Ohio, have invented a new and useful Pump, of which the following is a specification.
This invention relates to pumps; and it has for its object to provide a force-pump which shall be simple in construction, durable, and conveniently operated, and which shall be of such a nature as to enable it to be conveniently transported from place to place, thereby rendering it especially useful for the purpose of filling the water-tanks which are used for supplying the boilers of portable engines.
My invention consists in the improved construction and arrangement of parts, which will be hereinafter fully described, and particularly pointed out in the claims.
In the drawings, Figure 1 is a perspective View of my improved pump. Fig. 2 is a plan view of the same, with parts removed to show the construction more clearly. Fig. 3 is a transverse sectional view taken 011 the line a? 00 in Fig. 2. Fig. +1: is a transverse sectional view taken on the line y y in Fig. 2. Fig. 5 is a detail side view of the walking-beam and handle.
The same letters refer to the same parts in all the figures.
A designates the base of my improved pump, which is constructed with suitable supports or legs B B, and upon which is mounted the vertical cylinders O 0, one at each end of said frame. The cylinders are provided at their lower ends with lateral extensions D and E, in which channels (Z c are formed, respectively, for the admission and exit of the water, as will be seen in Figs. 3 and 4 of the drawings, the latter being connected with the cylinder at the bottom of the same, and the former is connected with the wall of the cylinder a short distance above the bottom. Connected to the extensions D and E are the valve-chambers F F, in which are arranged the check-valves G- G, opening upward and communicating, respectively, with the suction-pipe H and the exit-pipe I. The said suction and exit pipes are connected with the valve-chambers by means of T-couplings J, with which the upwardly-extending air-chambers K are in turn connected.
The valve-chambers and valves are of ordinary construction and need no further description. The air-chambers, likewise, are of the ordinary and well-known character. The base A is provided with a centrally-located upwardly-extending standard L, which is bifurcated at its upper end, as shown at M, and in which is pivoted the walking-beam N, to the end of which the piston-rods O O are pivotally connected. The lower ends of said piston-rods carry the pistons P, which are composed of cup-shaped disks secured by means of nuts Q on their under sides and around which packing R is wound above flanges S at the lower ends of said cup-shaped disks, as will be seen clearly by reference to Fig. 3 of the drawings. The packing is secured by means of the cup-shaped clampingdisks S, arranged above the disks Q, and adapted to be forced in adownward direction by means of the clamping-nuts T. In this manner the pistons may be constructed so as to fit tightly in the cylinders and without danger of making leaky joints, such as are oftentimes caused by the shrinking of the leather packing usually employed in this class of pumps. This construction also enables the packing to be easily removed whenever necessary. The cylinders are open at their upper ends for the passage of the piston-rods, which may be connected directly with the walking-beam, as described. The latter is provided at its ends with upwardly-extending brackets U U, between which are pivoted the cam-levers V V, which serve to retain in position the handle WV when the latter is placed in position upon the walking-beam between the brackets U U of the latter.
From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of my improved pump will be readily understood. By operating the walking-beam by means of the lever or handle attached thereto the pistons are reciprocated vertically in their respective cylinders. On the upstroke of each piston the water enters through the valve in the chamber connected to the extension D of said cylinder, while on the downstroke the water is forced from the cylinder through the channel or passage in the extension E, and through the adjacentvalve-casing and into the exitpipe. The air-chamber serves to insure the regularity of flow, and it will be seen that the entire construction of my improved pump is exceedingly simple and of such a nature as to render all of the Working parts easily accessible for the purpose of making any repairs that may be required. ing double-acting, as described, will throw a constant and heavy stream, and the general construction is exceedingly compact, thus rendering the pump conveniently portable. It will also be noticed that the operating-handle may be conveniently secured to or detached from the Walking-beam of the pump, as occasion may require.
Having thus described my invention, I claim- 1. In a pump, the combination of the base, the cylinders mounted upon the same and having lateral extensions provided with en- The pump, .be--
trance and exit channels, the valve-chambers connecting said channels, respectively, with .the suction and exit pipes, and the air-chambers ext-ending upwardly from the T-couplings,which connect the suction and exit pipes With the valve chambers or casings, substantially as and for the purpose herein set forth.
2. In a double-acting force-pump, the standard L, having the Walking-beam N pivoted thereto, combined with the handle WV, the cylinders O O, the piston O, and the cam-levers V, carried by the rods of the pistons to clamp against the handle W and bind not only the handle and walking-beam together, but also connect the pistons thereto, as set forth.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two Witnesses.
